Description

The miniOrange 2FA WordPress plugin before 6.2.7 does not restrict who can trigger its second-factor configuration OTP send, nor bind the OTP recipient to the enrolling user's own address, allowing a low-privileged user to send one-time-passcode emails to arbitrary recipients and to exhaust the site's metered OTP allowance, preventing legitimate users from receiving their second-factor codes.
